IDEA搭建SSM-Maven版
一、项目准备
1.准备工作
本次搭建是基于IDEA创建Maven项目-Web版之上进行搭建的，由于内容重复，故在此不做累赘直接跳过此部分工作。我这里的项目名是：MavenSSMDemo，你可以使用你自己的项目名称。
不知道如何使用Maven创建Web项目的小伙伴可移步：
IDEA创建Maven项目-Web版
2.完善项目
1.新建Java源代码文件夹，用来保存Java代码。操作流程：1.在main上右键->New->Package->填入Java->Java右键->Mark Directory as->Resource Root
2.新建views文件夹来保存jsp页面，添加的位置是在WEB-INF之下。
3.项目截图
上面都已经做好之后，项目的文件夹结构基本完整。下面跟着我一步步来搭建，要是有问题可以联系我，一般都是下班之后会给你回复。
二、创建项目
1.配置文件
1.user.mapper.xml
resouces下新建mapper文件夹，用来保存实体类的xml配置文件，在mybatis扫描的时候可以扫描到。
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.sjsq.model.user.mapper">
<select id="list" resultType="User">
select * from user;
</select>
<select id="selectUser" resultType="User">
select * from user where id=#{id};
</select>
</mapper>

三、数据库文件
drop database if exists maven-ssm-demo;
create database maven-ssm-demo;
drop table if exists `user`;
create table `user` (
`id` int(11) not null auto_increment,
`username` varchar(255) default null,
`password` varchar(255) default null,
primary key (`id`)
);
insert into `user` values (1, 'sjsq', '123456');
四、运行项目
浏览器输入：http://localhost:8080/list.do，就可以访问到页面了。
五、感悟及其他
1.感悟
SSM搭建过程，主要是配置文件要写正确。其次，要注意数据库的配置，这里使用的mysql8.0。其他就没有什么了。但是要理解SSM原理是较为复杂的，如果要是再读源码，要求就要更高。
2.商务合作
要是你自己对于本项目有定制化开发需求或者有什么其他问题，可以联系：
